SASH-FASTENER.

To all whom it may concer/a.'

Be it known that I, FRANK IV. BnAnns- LEY, a citizen of the United States, and a resident of `New York, Dongan Hills, Richmond borough, in the county of-Riehmond and State of New York, have invented certainnew and useful Improvements in Sash- Fasteners, which improvements are fully set forth in the following specification.

This invention relates to improvements in devices of that class quite extensivelyusecl at the meetingrails of, and for interlocking purposes in connection with, the customary upper andlower sash of a window, such devices being commonly known as sash fasteners.

The object of this invention is to provide a sash fastener' of the type above indicated, which shall be simple and comparatively inexpensive as regards construction; durable, and of marked efficiency in practical service; self-acting for a locking effect between said upper and lower sash, upon the latter being duly adjusted, each relatively to the other; which shall embody features of construction permitting manipulation of its operating parts, particularly for an unlocking effect, at the inner' face only of the sash in conjunction with which it is used; and

which shall possess certain well-defined ad-V vantages over prior analogous devices.

They invention consists in the combinations, details and parts whereby, together' with the novel disposition and relative `arrangement of said parts, the attainment of the foregoing `object is rendered practicable, all of which will be hereinafter more specifically referred to and set forth in the appended claims.

The invention is clearly illustrated in the accompanying drawings, wherein similar referenee-numerals denote like parts throughout the respective views, as to which:

Figure l is a plan view` of a sash-fastener embodying my said improvements, the same being` shown as generally applied to the meeting rails of the upper and lower sash of a window. Fig. 2 is a view similar to Fig. 1, showing the device detached from the sashrails aforenamed, the crown of' the main casing being removed and a portion of the crown of the keeper being-.broken away. Fig. 3 is an enlarged detail view, wherein Specication of Lettersatent;

Patentedivov. s, 1914. serial No. 740,911;

the main easing is shown in elevation with a portion of the side-wall and crown thereof broken away, and the keeper aforenalned 1s shown in central, transverse section. Fig. 4 is an enlarged detail view showing, independently of the main casing andl in sideelevation, the general trip-mechanism which .l purpose making use of,the same being reversed endwise from the position it is shown as occupying in Fig.` 3. Fig. 5 is an enlarged detail sectional view of certain parts or elements located centrally of the device and involved in the control and operation of the locking-button which I make use of.` Fig. 6 is a detail perspective view of said locking-button, detached.` i

I-Iaving reference to the accompanyingdrawings forming a part hereof, I purpose, in carrying out my invention, to make use of an inverted, box-like, main casing Q, disposed on the meeting-rail, as 2 of the lower sash, and held in position as by` means of the screws 2 2 and a keeper 3, disposed on the meeting-rail, as 3', of the upper sash, in registry with the main casing 2, and held in position as by means of screws 3 3.-`

4L is a vertical, rotatable pintle, arranged centrally of the casing 2, and having a suit-` able bearing,as at the point 4',

4: is a cap and 4 a locking-button, iixed, respectively, on the pintle at the upper and lower portions thereof, said cap being provided with a finger-piece 5, and said locking-button having a marginal riser a, arranged eccentrieallyto the pintle 4: and gradually diminishing in height from the heel to the tip thereof.

In the main, the keeper` 3 is-of an inverted, box-like form, and is provided with an interior lufr or tongue 5 which de ends s s P from the crown thereof. y

Thebutton 4 is` controlled by an elastic element, preferably in the formof a volute spring 5, fixedly attached` at one end, as at the point 5'", and attached at its opposite end, say to the pintle 4, thetendency of this element being, at all times, to elastically urge the button 4 into its locking position, `where the riser a takes more or less around and engages the lug 5', beneath the crown of the keeper aforenamed, thereby not only transfixing the upper and lower sash to which the device may be applied,

and in such a manner that the one may not be lowered nor the other raised, independ-- ently, but, by reason of the `eccentric form aforenamed of said riser, tending to draw said upper and lower sash snugly together, at the meeting-rails thereof, all as clearly indicated in lfig. 2 of the drawings.

l am aware that the construction thus far described is essentially old and well known in the art; also that trip-mechanism purporting to hold the locking-button of a sashfastener outif its locking position, and, through proper lowering of the lower sash relatively to the upper sash, automatically f release said button for a return movement into its locking position, has been heretofore availed of; but in this latter connection it is not rarely necessary, as a condition precedent to the setting or adjustment of any such trip-mechanism for a restraining effect on said button, that the lower sash be first somewhat raised relatively to the upper sash. This is objectionable, for the reason that, in practice, the user of such a fastener is required to hold, with one hand, the locking-button thereof out of its locking position, and at the same time attempt, with the other hand, to raise said lower sash, an operation frequently attended with much difficulty.

l overcome the above-named objectionable feature of prior analogous devices by employing, as a leading characteristic of my improved sash-fastener, and for coperation with the locking-button thereof, a constant-set trip-mechanism, by preference comprising substantially the parts Vand details which will now be described:

6 is a trip-lever working on the pivot 6', having a downwardly-turned tip 6", and provided with an upstanding dog 6"',the latter disposed to rock to and fro, as on the pivot 7. Said trip-lever is suitably recessed, as at 7', to measurably receive the dog 6"', substantially as shown in Figs. 2 anda, said dog having a flat bottom-surface against which normally iinpinges the free end-portion of the leaf-spring 7 attached to the trip-lever 6 at its under edge, and as at the point 7"', said spring tending at all times, accordingly, to elastically hold the dog 6' in a vertical position.

A supporting-arm 8, formed integral with, or otherwise fiXedly disposed relatively to the main casing 2, interiorly thereof, overlies the trip-lever 6 and serves to limit the upward movement thereof.

8 is a catch-lever, pivotally attached to the arm 8, at its free end. Said catch-lever is provided, at its advance end, with a catch 8", which coperates with the notch 9, here shown as formed in the bottom of the locking-button 4', said catch being held yieldingly to a sliding engagement with the bottom surface of said locking-button by means of a leaf-spring 9', whose free end, for this purpose, bears upwardly against the advance end of said catch-lever, The opposite end of the catch-lever 8 suitably overlies the dog 6"'.

It will now be observed that the lockingbutton aforenamed, the same having been duly swung against the tendency of its controlling spring, will be held against a return movement thereof in response to its controlling spring, by-reason of catch 8" entering the notch 9 and engaging the upright wall thereof, as indicated in Fig. 3; and this irrespective of whether the free end-portion of the trip-lever 6 be elevated or depressed. `When depressed, however, as will follow the suitable lifting of the lower sash of a window to which my improved fastener may be applied, the dog 6"' will automatically right itself, so that its upper free end will stand under the adjacent, overlying end of the catch-lever 8'. New, upon said lower sash being lowered, as to bring the top surface of its meeting-rail into registry with the top surface of the ineetinU-rail of said upper sash, the down-turned` tip ofthe trip-lever 6 engages the top surface of the meeting-rail of said upper sash,-the crown of the keeper aforenamed being cut away, as at 9", to provide clearance for the triplever 6, accordingly,and as said lower sash continues its movement downwardly, the free end of said trip-lever moves upwardly, with respect to the top surface of the meeting-rail of said lower sash, taking with it the dog 6', which, accordingly, trips momentarily the catch-lev-er 8', sufiiciently and in a manner to disengage its catch 8" from the notch 9, thereby releasing the locking-button 4', said dog, immediately thereafter, rocking out `of its engagement withl the adjacent end of said catch-lever, thereby releasing the latter, and permitting the same, under the action of its controlling spring, 9', to automatically reset itself for a further locking engagement with the locking-button 4', upon the latter being again duly moved against the tendency of its controlling spring,-this, even though the trip-lever 6 occupies its elevated position, `and eveny without lifting said lower sash. Upon the latter, however, being again duly lifted, trip-lever 6, either by its own gravity, or under the impulse of the spring 9', the latter, in this instance, being secured to said trip-lever, as at the point 8"', moves downwardly; dog 6"' again rights itself, beneath the adjacent end of the catch-lever 8', and upon said lower sash being again duly lowered, the foregoing operation is repeated. 1

The main casing 2 is provided with a socket 9"', which depends centrally therefrom, is open 'at its top, to permit the adjustment therein accordingly of the spring llO 5, and the pintle 4 bears in the bottom wall of said socket, as at the point fl, while the cap t` controls the mouth thereof.

It is to be understood that under releasement of the locking-button aforenamed as above defined, the same moves automatically into a locking engagement with the keeper aforenamed, and particularly the tongue 5 thereof, as clearly indicated in Fig. 2 of the drawing.

It will be seen that my improved sash fastener is well adapted for the purposes for which it is intended, and further that the same may be modified to a considerable extent, particularly as regards the specific elements made use of whereby the restraining of the locking-button aforenamed against the action of its controlling spring is etlected without the necessity of first lifting 'the lower sash, and as frequently prevails in prior analogous devices, all without departure materially from the scope of the appended claims.

I claim:

1. A sash fastener comprising a casing having a swinging locking-button; a keeper engageable by saidlockingbutton; a spring tending normally to urge the locking-button aforenamed into locking engagement with sai'd keeper, said casing and keeper being duly mounted, respectively, on the meeting-` rails of the lower and upper sash oi a win-` dow; a spring-controlled catch-lever adapted to lockingly engage, automatically, said locking-button, and temporarily hold the same retracted against the tendency oit its controlling spring, said catch-lever pivotally disposed independently of said lockingbutton, within the casing aforenamed; and a trip-lever, the latter pivotally disposed within said casing beneath the catch-lever a-torenamed, projecting from said casing into the plane of, and` overlying, the meeting--` ail of the opposite sash, and supporting in registry with the catch-lever thereabove an upstanding dog, the latter' being adapted, accordingly, to engage, trip and release said catch-lever.

2. A sash-fastener comprising a casing having a swinging locking-button provided with a notch; a keeper engageable by said locking-button; a spring tending normally to urge said locking-button into locking engagement with said keeper, said casing and keeper being duly mounted, respectively, on the meeting-rails of the lower and upper sash of a window; a spring-controlled catclnlever, adapted to lockingly engage, automatically, said locking-button at the notch thereof, and temporarily hold the same ret acted against the tendency of its controlling-spiang, said catch-lever pivotally disposed independently of said lockingbutton, within the casing afornamed; and a trip-lever, the latter pivotally disposed within said vasing, projecting somewhat therefrom into the plane of the meeting-` rail of the opposite sash, overlying the latter and underlying said catch-lever, and having pivotally attached thereto a springcontrolled dog, said dog adapted, upon the free end of said trip-lever being elevated, to engage, trip and release said catch-lever, whereby said locking-button is freed to automatically respond to the impulse of its controlling-spring.

3. A sash-fastener comprising a casing having a socket depending centrally therein from the crown thereof, said socket formed integral with said easing, and access to whose interior is essentially had only at the open-top thereof; a pintle disposed to rotate axially within said socket, said pintle projecting downwardly through, somewhat beyond, and bearing in the bottom wall thereof; a spring let into said socket from the top thereof, and encircling and controlling said pintle; a locking-button fast on said pintle, at its lower end, beneath said socket; and a cap, the latter fast on, and aifording an additional bearing for, said pintle, at its upper portion, overlying and closing the open top of said socket, and provided with a finger-piece.
